Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | ones | . | tenths | hundredths |
| 8 | . | 9 | 9 | |
| × | 0 | . | 1 | |
| . |
Ignore the decimal points and multiply as if these are whole numbers (as if each most right digit is the ones digit):
In this case we removed 3 decimal place(s). So once calculated, the result will be reduced by the factor of 1,000.
| Place value | hundreds | tens | ones |
| 8 | 9 | 9 | |
| × | 1 | ||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (1) of the multiplier 1 by each digit of the multiplicand 899, from right to left.
Multiply the ones digit (1) of the multiplicator by the number in the ones place value:
1×9=9
Write 9 in the ones place.
| Place value | hundreds | tens | ones |
| 8 | 9 | 9 | |
| × | 1 | ||
| 9 |
Multiply the ones digit (1) of the multiplicator by the number in the tens place value:
1×9=9
Write 9 in the tens place.
| Place value | hundreds | tens | ones |
| 8 | 9 | 9 | |
| × | 1 | ||
| 9 | 9 |
3. Add the partial products
Multiply the ones digit (1) of the multiplicator by the number in the hundreds place value:
1×8=8
Write 8 in the hundreds place.
| Place value | hundreds | tens | ones |
| 8 | 9 | 9 | |
| × | 1 | ||
| 8 | 9 | 9 |
Because we have 3 digit(s) to the right of the decimal point in the numbers that are being multiplied, we move the decimal point 3 time(s) to the left (reducing the result by the factor of 1,000) to get the final result:
The solution is: 0.899
